When I was a kid, I used to play a game called “Robotech”. In this game (a boardgame, fancy that!), players controlled giantic robots called “mechs” that were piloted by humans. One of the armaments you could arm your mech with was a railgun, and if I remember correctly, it was pretty nasty.
It’s downright weird how science fiction can become reality.
Thanks for posting this. Not only was this very interesting, but it brought back a fun memory.
Artists dream the future that engineers then create. Interesting how that works.
